850 W ATX Server Power Supply

This 850 W ATX server power supply delivers up to 850 watts of continuous power for demanding workstation and server builds. It carries 80 Plus Gold certification for high efficiency across typical loads. The unit operates on 110–240 V input at 50/60 Hz and weighs 1.9 kg.

Full modular design for custom cable routing

The fully modular layout lets builders connect only the cables their system requires, reducing clutter and improving airflow inside the chassis. A single 120 mm hydraulic-bearing fan handles cooling. Systems needing redundant power supplies or a different form factor should consider other options.

20+4 pin main connector with 12 V support

The 20+4 pin main connector and dedicated 12 V output ensure compatibility with modern motherboards and graphics cards. Active PFC maintains stable power delivery across the 110–264 V input range. Dimensions are 150×140×85 mm for standard ATX fitment.

Questions about this item

Will the 120 mm hydraulic-bearing fan need replacement after long-term use?

The 120 mm fan uses a hydraulic bearing designed for extended operation; under normal conditions it should not require scheduled replacement, though dust buildup can reduce airflow and may warrant occasional cleaning.

What limits the 850 W output during continuous heavy loads?

The single-rail 12 V design is rated for 20 A, so sustained draws above that current or prolonged operation near the 850 W ceiling will trigger over-current or over-temperature protection first.

How loud and hot does the unit get when running all day at high load?

The 120 mm hydraulic-bearing fan spins faster as internal temperature rises, so noise increases with load; active PFC and 80 Plus Gold efficiency keep waste heat moderate, but the 1.9 kg chassis will become warm to the touch.
